Genesis 42:6

“And Joseph [was] the governor over the land, etc.] Not the land of Canaan last mentioned, but the land of Egypt; under Pharaoh, he had the chief and sole authority, and especially in the affair of the corn, and the disposal of that; [and] he [it was] that sold to all the people of the land: of Egypt, and also to all that came out of other lands; not that he in person could do all this, but by those that acted under him: and Joseph’s brethren came; to Joseph to buy corn of him: and bowed down themselves before him, [with] their faces to the earth; not only bowed the knee as the Egyptians did, but prostrated their whole bodies, stretching out their hands and feet, and touching the ground with…”

Joseph recognized his brothers immediately, but he could not reveal himself because he did not yet trust them to be the honest men they claimed to be (42:10).”
